+ * nf_tables used to have five registers: a verdict register and four data
+ * registers of size 16. The data registers have been changed to 16 registers
+ * of size 4. For compatibility reasons, the NFT_REG_[1-4] registers still
+ * map to areas of size 16, the 4 byte registers are addressed using
+ * NFT_REG32_00 - NFT_REG32_15.
